I. THE CASE

Your training stack, finally under one roof.

Most athletes pay for a tracker, then a calendar, then a coach, then a social feed, then a strength app — four tabs open, four subscriptions, none of them talking to each other. SPLIT replaces the whole stack with a single account that actually plans your week off your real data.

The platform is built for runners and endurance athletes who want real data, real coaching, and a tool that actually helps them improve — not another dashboard that looks pretty and ships nothing to the watch. Every number you see has a mechanism behind it, every chart has a calculation you can audit, every plan is periodised around your registered races.

01
Everything in one place.

Live GPS recorder, Garmin sync, training plan generator, AI coach, strength log, route builder, friend feed, challenges, race predictor.

02
Less than any single tool.

Premium is $8 a month, or $80 a year. Below the monthly price of almost any single piece of the stack you’re probably running today.

03
Your data belongs to you.

European servers. Full bulk export to CSV and JSON. No upsells that lock your history behind a paywall.

04
Plans that read your training.

Adjusted for VDOT, FTP or CSS. Recovery-aware. Sport-specific engines, not a running plan under a different label.

III. ORIGIN

Built for athletes.

SPLIT started as Mark’s personal training dashboard on the road to a sub-80 Copenhagen Half Marathon. It grew into a full platform once the core engine proved it could actually help someone hit a real race goal.
